PH Monitors

[trilinearmipmap]

I have 2 American Marine Pinpoint monitors, one on my reef tank and one for my calcium reactor. The monitors work well and are easy to calibrate.

I question whether anyone really needs a pH monitor on a reef tank. If you are measuring your Alk and your Alk is high enough, your pH should automatically be OK. I have come to the conclusion that my fish and corals don't care what the pH is and I focus on Alk, not pH.
